We had a number of short comings:

- EEE must be re-evaluated whenever the state machine detects a link
 change as wight be switching from a link partner with EEE
 enabled/disabled

- tx_lpi_enabled controls whether EEE should be enabled/disabled for the
 transmit path, which applies to the TBUF block

- We do not need to forcibly enable EEE upon system resume, as the PHY
 state machine will trigger a link event that will do that, too

It doesn't look like this one applies to 5.15...


Yes I based it off an incorrect branch that has additional changes queued up locally, v3 coming shortly, thanks!
